Description

A kind of dual-purpose precision seeder
Technical field
The utility model relates to a kind of agricultural machinery apparatus, especially a kind of precision seeder.
Background technology
Sowing is a link the most basic in agricultural production process, and the quality of seeding quality is the prerequisite of emerging, keeping a full stand of seedings and increasing production.Along with the development of agriculture production technology and the renewal of seeding technique mode, the precise sowing technology of China and precise sowing machinery had had development at full speed in the last few years.Precision seeder is the core work position of precision planter, and its seed-metering performance has direct impact to seeding quality.
In seeding process, precision seeder is separated seed from kind of case, is discharged in kind of ditch each other by simple grain with certain adjustable spacing.Can be divided into two large classes by seeding principle: a class is mechanical accurate seeding apparatus, according to seed grain type, utilize the type hole on the seeding wheel disc in seeding unit, spoon or refer to press from both sides etc. is separated seed from kind of case, fill kind, the links such as clear kind and seeding are to rely on self gravitation or the mechanical device of seed to complete, mechanical accurate seeding apparatus is simple in structure, easy to manufacture, cheap, but the size and dimension of seed is required strict, versatility is poor, mechanical accurate seeding apparatus mainly contains Horizontal disc, inclined plate formula, nest eye is wheeled, inclination scoop-wheel, inside fill hole roller formula, vertically turn a spoonful formula, finger-clipped and belt etc., another kind of is Pneumatic precision seeding unit, normally drive blower fan by tractor dynamic power output, produce pull of vacuum or air pressure, make seed be attached to and on type hole, fill kind and clear kind process relies on strength to complete, Pneumatic precision seeding unit injuring-free seed by simple grain, require not strict to seed sizes, versatility is good, can adapt to higher farm work speed, but manufacturing cost is high, in use procedure, easily break down, Pneumatic precision seeding unit is divided into again air-sucking type, air-sweeping type and vapour-pressure type.
Pneumatic precision seeding unit mainly uses on medium-and-large-sized precision planter, and what on miniature seeding machine on the market, use is generally mechanical accurate seeding apparatus.Mechanical accurate seeding apparatus again, scoop-wheel wheeled taking nest eye and finger-clipped, as main, is generally applied in the sowing of seed of the large grain such as corn, soybean.Than the wheeled precision seeder of nest eye, scoop-wheel and finger-clipped precision seeder are welcome by peasant more, they use simple, simple grain rate height and the hole rate of seed are low, rapider in development in recent years, need improved aspect but also exist, for example, before the adaptability to the large seedlet of difference, sowing, need that seed is screened and plant clearly efficiency low etc.And some peasant is in order to carry out the sowing of different seeds, has bought scoop-wheel and finger-clipped precision seeder two complete equipments, needs in use to change a whole set of equipment, not only, for sowing has brought inconvenience, also increase peasant's financial burden.
Summary of the invention
The purpose of this utility model is to provide a kind of dual-purpose precision seeder, strengthens the adaptive capacity of seeding unit to the large seedlet of difference, improves clear kind mode, allows user can under same seeding unit main body, carry out the conversion of scoop-wheel and two kinds of seeding modes of finger-clipped.
The utility model mainly comprises seeding unit main body, speed changer, seeding unit axle, scoop-wheel dispenser, finger-clipped seed wheel and seeding unit end cap, described speed changer is arranged on a side of seeding unit main body, described seeding unit axle is connected with speed changer, described scoop-wheel dispenser comprises leads kind of a wheel, dividing plate and seeding bucket wheel, be enclosed within from inside to outside successively on seeding unit axle, dividing plate is connected with seeding unit main body, leading kind of wheel and seeding bucket wheel is connected on seeding unit axle, described finger-clipped seed wheel is arranged on seeding unit axle, seeding unit end cap is arranged on the opposite side of seeding unit main body, solving the technical scheme that its technical problem adopts is that scoop-wheel dispenser and finger-clipped seed wheel can be replaced mutually, but can only select one to install, there is one section of screw thread the end of seeding unit axle, there is a regulating handle to be arranged on the screw thread place of seeding unit axle, can inwardly screw, between finger-clipped seed wheel and seeding unit main body, be provided with a Compress Spring a, at seeding bucket wheel and lead and be also provided with a Compress Spring b between kind of wheel.
Preferably, described Compress Spring a is fixed on the center, the back side of finger-clipped seed wheel.
Preferably, there is the cylinder shape groove of placing Compress Spring b in described centre, the seeding bucket wheel back side.
Preferably, described seeding unit main body is provided with a clear mouth of planting, and at the clear mouthful place of planting, a seed clearing wheel is set.
Preferably, be provided with 18 get kind of a groove on described finger-clipped seed wheel front along even circumferential, each getting on kind of groove is provided with small one and large one two through holes, arranges and refer to folder post in macropore, arranges and plant clearly post in aperture, plants clearly post and is connected on finger folder post.
Preferably, the first half of described seeding unit main body wall is provided with a groove along circumference, and groove is wide is 3-5cm, the degree of depth of groove is along circular arc gradual change, reach the darkest at circular arc top, and shoal gradually to both sides along circular arc, until get back to the height concordant with seeding unit main body wall.
